The Do-Drul Chorten or Stupa was built by the Venerable Trulshi Rimpoche, head of the Nyingma order of Tibetan Buddhism in 1945. Inside this stupa, there are complete mandala sets of Dorjee Phurba (Bajra Kilaya), a set of Kan-gyur relics (Holy Books), complete 'Zung'(mantras) and other religious objects. Around this Chorten, which is one of the most important stupas in Sikkim, are 10 Mani-Lhakor (prayer wheels). These prayer wheels are turned by the devout Buddhist while chanting "Hail to the jewel in the Lotus", to invoke the Buddhisattva. The Chorten is surrounded by Chorten Lakhang, where there are two huge statues of Guru Rimpoche (Guru Padmasambhava).
